The garments definitely help with postural support as they encourage optimal horizontal extension and retraction of the Scapulae, (upper central key points) giving a Scapulothoracic neutral posture. The value in this for function is to lessen kyphotic stress in the primary curvature which physiologically eases counter-stress in the secondary curvature of the segments. The wearer should therefore be aware of less effort and mechanical stress particularly with prolonged standing or sitting and may, indeed, notice improved ergonomics with upper limb activity.
